Wonder what it's like before Reba McEntire and Brooks & Dunn take the stage at the Colosseum at Caesars Palace? Get an inside look at how the country superstars prepare for their Las Vegas residency, which kicked off on Wednesday (June 24).

The video clip begins with the three singers rehearsing the duo's 1995 hit "You're Gonna Miss Me When I'm Gone," from the previous year's Waitin' on Sundown album. Interspersed throughout the video is footage of the gorgeous Caesars Palace, merchandise for sale, including mugs and records, and signs throughout the venue that feature the three stars. McEntire and B&D are also shown during soundcheck and taking photos with fans, all while cracking jokes and having a good time.

The three singers take their residency extremely seriously, calling it a "huge responsibility."

“It’s a huge building, lots of seats out there. I think it’s a big load off my mind to have these guys with me, and visa versa," McEntire says, adding, "It will be a production show, a country show packed with No. 1 hits. One of them will wear the red sparkling sequined dress. This is better than cake and ice cream!”

The trio added more dates to their time in Sin City after a chunk of their original dates sold out. The Reba, Brooks & Dunn: Together in Vegas show is the first time that Kix Brooks and Ronnie Dunn have shared a stage since their breakup 2009.

"Honestly, it’s funny. I think one of the real rewards for doing this is, not a day goes by where somebody, in a very emotional way, says, 'Why don’t y’all get back together?'” they said earlier. “To be able to go, ‘We are, we’re going to be in Las Vegas next summer,’ it’s a relief to have a decent answer. It’s a soft landing and a soft takeoff.”

McEntire, Brooks and Dunn will be playing at Caesars Palace in June, July and December, but they aren't shooting down the possibility of a long-term residency either. Tickets to see the Las Vegas show are available on Caesar Palace's website.
